Continuity Test; G) Capacity Measuring - VOLTCRAFT VC950 Bedienungsanleitung

f) Continuity Test
Make sure that all circuit parts, circuits and com-
ponents and other objects of measurement are dis-
connected from the voltage and discharged.
- Switch on the DMM and select the measuring range
Press the button
The symbol for continuity test now appears in the display.
Pressing this button again takes you to the next measuring
function, etc.
- Plug the red measuring line into the Ω measuring jack (7) and
the black measuring line into the COM measuring jack (8).
- A value of less than 50 Ohm is measured as continuity and a
beep sounds. The measuring range is up to 400 Ohm.
- If "OL" (overload) appears on the display, you have exceeded
the measuring range or the measuring circuit is interrupted.
- Always remove the measuring lines from the object to be mea-
sured after completion of the measurement and switch off the
DMM.

g) Capacity Measuring

Make sure that all circuit parts, circuits and com-
ponents and other objects of measurement are dis-
connected from the voltage and discharged.
Always observe polarity with electrolyte capaci-
tors.
- Switch on the DMM and select the measuring range
the rotary control (4). Press the button
switch measurement functions. The display shows the unit
"µF". Pressing this button again takes you to the first measu-
ring function, etc.
- Plug the red measuring line into the V measuring jack (7) and
the black measuring line into the COM measuring jack (8).
Due to the sensitive measuring input, the display may show
a value if the measuring lines are "open". By selecting the
function , the display is set to "0".
The basic value (rel difference) is displayed in the upper,
small display. The autorange feature is deactivated.
- Now connect the two measuring prods (red = plus/black = minus) with the object to be measured (capacitator).
After a short time the display shows the capacity. Wait until the displayed value has stabilised. This may take a few
seconds for capacities of >40 µF.
- If "OL" (overload) appears on the display, you have exceeded the measuring range.
- Remove the measuring lines from the object to be measured after completion of the measurement and switch off
the DMM.
